The Ornamental Plant Germplasm Center (OPGC) is part of the National Plant Germplasm System, a network of organizations and people dedicated to preserving the genetic diversity of crop plants.

The OPGC is a joint effort of the USDA-ARS and The Ohio State University's Department of Horticulture and Crop Science.  Financial support is provided through the Floriculture and Nursery Research Initiative of the ARS.

Mission and Goals

Our mission is to conserve genetically-diverse herbaceous plant germplasm and associated information,  conduct germplasm-related research, and encourage the use of germplasm and associated information for research, crop improvement and product development.   

Our goals are to acquire, document, maintain, characterize and distribute herbaceous ornamental genetic resources and associated information for conservation, and to enhance scientific research as well as the floriculture and nursery industry.
